 nobility,
And every man is a friend to
one who gives gifts

My son, if you become surety for  your friend,
If you have shaken hands in  pledge for a stranger,
You are snared by the words of  your mouth.
So do this, my son, and deliver  yourself;
For you have come into the  hand of your friend:
Go and humble yourself; 
Plead with your friend.
Give no sleep to your eyes,
Nor slumber to your eyelids.
Deliver yourself like a gazelle
 from the hand of the hunter,
And like a bird from the hand of the fowler.
